Great scene, the last lecture we had a definition of the information security.
Now, as I already mentioned, in the definition of information security, the three main core principles
of information security are the CIA right now.
Let's have a look at the CIA.
Right now, the CIA dryad consists of three important security elements of confidentiality, integrity
and availability.
Now, in this lecture, we are going to just have an overview of the CIA tried.
So the availability stands for property of being accessible and usable on demand by the authorized entity,
which means if there is a data now, if that data is being accessible and usable on demand by any authorized
person, then we can see that the data is being followed, the property of availability.
Next comes confidentiality, which means if the data that the information is not disclosed to unauthorized
individuals, which means the data is only accessible to authorized individuals, then they can see
that the data has been following confidentiality, principle and integrity.
Is that the property of accuracy and the completeness of the data?
Now, don't worry.
If you haven't yet understood these definitions in depth, we are going to see each and every definition
in the upcoming lectures.
I just wanted to give you an overview of the site.
Right.
There are also other factors like authentication, authenticity, accountability, non repudiation and
others.
But all it pinpoints to the CIA tried only.
So whenever you are going to appear for your interviews, make sure that you are completely aware of
the CIA tried because you interview me, ask you about DCI Dry-eyed.
Let us begin with the first element of confidentiality.
